1. FOURIER AND REVERSE FOURIER OPTICAL SYSTEM
The Bettersizer 2600 is superior in the combination of Fourier and inverse Fourier design. This smart design allows, on the one hand, the detection of stray light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to the inverse Fourier design, the particles do not have to lie on one plane – the simultaneously accurate measurement of small and large particles is therefore achieved.
Features of combination of Fourier and inverse Fourier design
Spherical detector array: Forward, lateral and backward detectors in 92 pieces in total;
Super large Fourier lens;
Small footprint: Compact design to save space
2. INTUITIVE AND POWERFUL SOFTWARE
Intuitive operation and orderly user interface
Real-time mode for determining the optimal measurement conditions
Fully automatic measurement routine
Automatic cleaning routine
Automatic data backup and highly customizable reports
Direct conversion according to Fraunhofer and Mie evaluation models
Switch between wet and dry dispersion modules with one click
3. WET DISPERSION
BT-802 is designed for particle size measurement with water as the medium.
BT-802 is made up of ABS shell. The components of it include centrifugal pump, peristaltic pump, ultrasonic disperser, pinch valve, control circuit, etc. The stirring speed is adjustable from 500 - 2500 rpm. Built-in ultrasonic system (50 W) ensures stable dispersion of samples.
4. DRY DISPERSION
BT-902 is suitable for dry powders particle size measurements. The gas used can be compressed air, nitrogen or other noble gases.
BT-902 is made up of electromagnetic vibration feeder, venturi pipe, gas circuit, electric circuit, pressure sensor, etc.
